MEANS OR APPLINCE FOR TRANSMITTING FLUID UNDER PRESSURE.

To @ZZ whom it may concern,.-

Be it known that I, STEPHEN H.; BROOKS, a citizen of the United States of America, residing in the city of. Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in Means or Appliances for Transmitting Fluid 'under Pressure; and I herebyl declare the following to be a full, clear, and exact description there-v of, reference being'had to the accompanying drawings, making a part of this application.

My invention relates-tothe general type of the class with which it is concerned, wherein a tubular reservoir or supply-duct carrying the luid under pressure is enabled to variantly serve a movablemotor or implement by means of a traveling receiver that surrounds said reservoir and actuates valves therein,which said valves guard a corresponding series of ports against the escape of the uid in question. In all devices of this kind, so far as I am aware, the said valves are connected with tappets projecting from the under side of said reservoir in suitable relations to be encountered and actuated by the approaching receiver and by such contact to actuate the Valves themselves. Arrangements of this kind are open to certain constructive and operative disadvantages that it is desirable to overcome-as, for instance, the tappet connections referred to are somewhat complex in detail and must be located as to their chief parts within the reservoir itself and at each and every port or aperture p. This involves both a considerable cost and also exposes the parts to deterioration in consequence of the moisture of the Iiuids with which they are necessarily constantly surrounded. So, too, in said devices the tappet connections are actuated solely by the impact of an inclined projection on the moving receiver, and consequently a nice degree of adjustment of all parts is requiredto insure' a uniform operation at every point.

It is the object and aim of my present invention to Aprovidefan appliance of the class in question that is free ,of these defects and is at'the same time simple in construction and positive in operation. I accomplish such purpose by the apparatus I shall now proceed to more fully describe, referring to the accompanying drawings, wherein similar parts are designated in each case' by the same letters.

Figure I is a sectionalview of al construction embodying my invention through the longer axis ofthe receiver involved. Fig. Il is a like sectional-yiew, enlarged, of a portion of such receiver when slightly advanced on its reservoir toward the right from the relative position'of the two parts in Fig. I. Eig.v III is an enlarged vertical sectional view through the dotted line III III in Fig. I; Fig. IV, a like View through the dotted line IV IV of said igure. i

A is the reservoir or supply pipe of the fluid to be transmitted to a movable motor or implement. It is ordinarily tubular in shape and is provided on the under side throughout its length with a series of ports or apertures pp. These -ports or apertures may be locatedwith any desired intervals; but it will be found preferable to have such intervals not greater `than the interior of the receiver, hereinafter described and as in the drawings, so that two may be brought within said receiver at the same time. Said ports or apertures areY guarded by gravityvalves V V, which may be protected against lateral displace ment by an open-worked covering-piece O.

R is .the'receiver, which is made up of a sleeve or tubular fitting S and a depending chamber C. The sleeve S is bored out to a diameter slightly greater than that to which the reservoir A turns down and is slipped over said reservoir and properly packed at each extremity.

D D are cross-pieces or pins, having their ends mounted in oppositely-located bosses b b within said chamber. Said cross-pieces sus tain spring-seats c c, penetrated at an operative fit by -spring-rods e e, that carry helical springs g g, bearing upwardly in each case against a second spring-seat c. These second spring-seats c c' are forked at their upper ends to receive sliding shoes or rockers B B, that are held inl such position by the hinge-pins and guides G G.

As appears in the drawings, I preferably give said hinge-pins downwardly-extending elbows that respectively enter lateral recesses F F in the chamber C. Said recesses have Vertical dimensions equal to the up and- IOC down travel or play of the spring-rods e e, which, aswill be understood, must be such as will allow the sliding shoes B B to be projected upward by the helical springs g g through the ports or apertures p p when brought beneath the same. I provide a stop tat the lower end of the spring-rods c c to limit its upward travel and give to the shoes B B a downward projection to their front in order to thereby engage with the lower edge of the ports p p and depress the shoe out from a port it may have entered and into the chamber C.

I find it desirable to furnish as many as four of the valve-operating spring appliances just described in the chamber C, arranged in alinement through the same, in order that as the receiver is advanced along the reservoir a sliding shoe B shall take on with respect to a given valve as its immediate predecessor is taking oit therefrom. By this arrangement a continuous flow ot' the compressed fluid is assured.

N is a neck to which a hose or other form of conduit may be attached and connected with the further transmission-terminal. Although in the specific device chosen forthe drawings this neck is shown as located below the receiver R, it is plain that it may be prolonged to a point at the top or intermediate of the top and the lowest part of said receiver, according as may be best adapted to the special conditions inrwhich the device is to be used.

The appropriate method of using my said device will be manifest, it is thought, from the foregoing description. The receiver R, having been introduced about the reservoir or supply-pipe A, is connected at the neck N with the conduit leading to the machine or implement to be supplied. According as said machine or implement is moved from one point to another the receiver is advanced in the one direction or the other along the reservoir A. In this movement the several shoes B B B B are successively brought beneath t-he gravity-valves V V when the tension of the springs g, forcing their respective shoes upward against said valves, will raise the latter and thereby permit the escape of the duid from the reservoir into the chamber C, and thence out through the neck N. As said receiver and its set of sliding shoes are further advanced the foremost in the alinement will pass entirely from beneath a valve, but not before the next in succession has gained a position to prevent the closing of such valve, and so on until a new series of valves have been brought within the receiver and are in like manner actuated by said springs and shoes. As the new series of valves is thus encountered by the receiver R the former s'eries have in the meantime one by one been left behind the same, and each valve as it has thereby been relieved from upward pressure by said shoes has automatically fallen into its -mission seat and closed its port p against further escape therethrough of the duid under trans- On the other hand, the valves in the new series when located at equal intervals not exceeding the receivers length will simultaneously be opened, and when thus 1ocated, as will be evident, a continuous transmission of iluid will be maintained.

Having thus explained my said invention as embodied in an operative device, what I claim, and desire to secure by Letters Patent, 1s-
